Super Precision Angular Contact Ball Bearings S71914 ACD/P4ADBB

Super Precision Angular Contact Ball Bearings S71914 ACD/P4ADBB

The S71914 ACD/P4ADBB is a super precision angular contact ball bearing with a 70mm bore and 100mm outer diameter, crafted from high-quality chrome steel. Its compact 32mm width and 25° contact angle make it ideal for handling combined radial and axial loads.

This sealed bearing set (two matched units) offers smooth operation at speeds up to 28,000 RPM, with a dynamic radial load capacity of 11858 lbf. The phenolic cage ensures quiet performance, while grease lubrication simplifies maintenance.

With P4A tolerance class and light preload, it delivers excellent rotational accuracy for demanding applications. The bearing performs reliably in temperatures from -30°C to 110°C.

Perfect for precision equipment like machine tool spindles or high-speed robotics, where both speed and accuracy matter. At 0.67kg per bearing, it balances strength with manageable weight.
